Xcode crashes on startup

With one particular Xcode project, my Xcode will launch, go through the usual startup (build, find working copies, etc) sequence then after the progress bar stops moving it abruptly quits. This section always seems to be in the crash logs:

I've tried running the Xcode uninstall script and re-installing from the App Store, so I don't think my installation is the issue. I'm running OSX 10.7.1.

I re-created the project with git clone and I was able to open the project again. I suspect that the xcodeproject file was corrupted somehow, perhaps a bad conflict resolution.
